PROBLEM TO BE SOLVED: To suppress losses in a diode as much as possible, even in electronic equipment in which plural power sources are connected in a diode OR system. SOLUTION: Plural power sources 1, 4, and 7 are connected in parallel, and diodes 2, 5, and 8 are connected serially with each power source, so that diode OR output can be obtained in this electronic equipment. In this case, a switching means 20 is connected in parallel with one of diodes 5, and the switching means 20 is turned into a conductive state when the power source 7 other than the serially connected power source 4 to the diode 5, to which the switch means 20 is connected in parallel, present. |
